It is evident herefrom that when all'latter depress or raise the bearings L. The

said bearings must be provided lwith an oblong when the-latter turns,and

will now proceed ,to describe the manner 111 which the srews'c c' c2 c3d d' d2 and the cam-disks K K .are driven, without, howev`"er, atpresent taking into account the reversing of motion ofthe machine.v

0n the end ofon'e ofthe journals of the roller A it fixed the pinion a,which gears with the wheel b on the counter-shaft o, (see-v Fig. 5,)while the wheel b', keyed on the same shaft, is in gear with thev pinionu', placed loose'on the roller A.' The wheels band bbeing of differentdiameter, as also the pinions a and a', the said pinion a' will rotateon the roller will consequently cause the rotation of the pinion a2,made in one piece with a'. the pinions e, fixed on'the ends of thescrews c o'- c2 c3, and thus puts all these screws in uniform rotation.The mechanism serving to A drive the v*screws of the roller B is likethe ed in arms one described. (The sam'ehas therefore been omitted inFig. 1;) lt may, however, be observed that the counter-sh aft projectingfrom the movable bearing L.

The rotation of t-he shaft'H, which drives .the cam-.disks K by means ofthe worms H' and the worm-wh eels J",'is caused by the'wheel G, placedon the said shaft and gearing with the wheel E. The spirals, accordingto which the ribs of the cam-disks K are arranged, must be so formedthat for a given angle between two radii theditference of these radii isgreatest at the outer end of the curve, while 'it gradually decreasestoward the inner end. The reason herefor is the following: When thespeed of rotation ofthe rollers is uniform the'screws f ofthe same willalso rotate uniformly. Colisequently the corrugating-rin'gs will beshifted in equal periods of time bythe same amount. Fora givenunit ofthis shifting motion the amount by whichthe corrugating-rings DD' D2penetrate into the spaces between the rings C G' C2 O3 must at thebeginning be greater than toward the end of the operation, because atthe outset of the forming of acorrugation the increase of depth of theinflection 'Iss rollers 4the plate pass'alternately forward and backisgreater than toward its completion, provided always that thecorrugations are to be-produced.

by bendingonly. The form of the curve of the cam-disk may be determinedby calculation or` Iby drawing.

Considering that the ad justmentof the upper roller and ofl the'corrugating-rings must take` place while the machine ism-operation, thecorrugations willat'rst become taperedi. e., they will be deeper andnarrower at the end ot' the plate last exposed to the action of the wItis therefore advantageous to let ward between the rollers until thecorrugations have attained 'the desired depth; For

The pinion a? gears-with thereof is mou nt- "blepnly causes noinconvenience, as the reversal need upon. Itis therefore necessary toreverse these' mechanisms in their turn after the whole machine has beenreversed, so that in consequence of vsuch double reversion they willcontinue to 4work in the same direction. For attaining this object thewheel G, driving the worms H', is fixed on a'psleeve,xG2, the endswhereof form couplingboxes, which' can engage with the coupling-boxes land l', respectively, fixed on the shaft H.. Moreover, a wheel, G',rotating loose on an axle, G3, and gearing with the wheel E, isprovided, which may be shifted-simultaneously with the'sleeve G2 and thewheel G, but in the contrary direction,l by means of a double-armedforked lever, l2, as shown by Fig. 1. The parts being in the positionrepresented by drawings, E actuates the shaft H in one direction bymeans of the wheel G and couplingbox l',while the wheel G', gearing atthe edge with E, turns loose on its axle. When the lever l2 is put intoits other position Gis shifted but though the motion of the rollers be'to the right, while G, being shifted to the left, j

comes out of gear with E and into gear with G', so that G will nowrotate in asensey contrary to its previous rotation, provided Evcontinues to turn `in thesamedirection. The left-hand into engagementwith the teeth of the coupling-box l, the shaft H will also rotate againwith the wheel G. e While this reversal is being carriedout the threewheelsE, G, and G' will ata certain moment all be in gear with eachother. The reversal is therefore possiwhile the'machine is at rest; butthis teeth of the sleeve" Gzhaving finally been put roo only b e carriedoutfduring the stoppage occurring vwhen the plate has arrived'witheither of its ends near to the rollers, and the direction of motion .fofthe latter has to be changed. Y

4The mechanism iorreversing the motion of the screw-spindles isv similarto th'e'described arrangement. The wheels a, -b,and` g correspondrespectively to the wheels E,G, and G',

the lever t' to the lever l2, and the sleeve b2 to the sleeve G2, In thelikle mechanismfor the roller B (which hasnot t the wheel corresponding,tog rotates-on a pin carried by an arm cast together-with thecoverofthe bearing L.

when being driven by G' will it immediately. come into gear with E afterG2 has been dis- The sleeve may thus be put out causing a rotation ot'the shaft H. In an analogous manner the transferrin'glwheels ab g andthe teeth of the sleeve buas well as ot' the coupling-boxes on 4theshaft o, are brought in relation to eachother, (ofcourse in respect toboth rollers A and B.) Thus the cam-disks `K,'as well as theregulating-screws ofl all the corrugating-rngs, may simultaneously beput out ot' operation w-hile the rollers rotate.`

Fig. 6 shows an arrangement' for corrugating and at the same timebending plates' transversely to the ccrru'gations. The same consists, asin other machines of this kind, of a combination of two adjustableauxiliary roll ers, A and A2, with the rollers A ahdB; but the rollers Aand A? are provided with movable corrgatingrings in the same manner as`the roller A.

'lbedevices for -iadjustin 0 theupperrolierfm and thecorrugating-rings-may be modified in In the first place thecorrugating-rings may be guided'on both sides by forked slide-blocks, whichfiutheir `turn are guided parallel tothe rollers, and throughwhich theregu'latih/gfscrews pass in asimilar manner as hasfbeen describedinrespect to the corrugating-ringsshownin the; drawings. Moreover, theseslideblocks Vmay be connected together iby a system Vof crossed levers,called lazytongs,7 the common pivot ofeach pair ot'crossed levers beingtixed 4in a slide-block, while the Ajointsat the ends et' the leversarein the vertical center line of vthe space between two blocks: 11n thiscase but one screw on'eithcr side is-required for shit'tin g theslide-blocks, together with-the vcorrugating-rings; also, twoarmedlevers might be used having arms of different length, each, of thesellevers'- acting with one end on aslide-block, while their other ends aremoved uniformlybyascrew, .[Illothe arms of-these 'levers suchproportions would have to be given as Aare necessary `forimriarting tothe slide-blocks the requisite motionf ln some cases` theregulating-screws of the' ar,- rangement represented`by drawings may beplaced inside of the rollers,'provided these be 6o' made hollow.

.Instead of the described camidisks lby which the vertical adjustment ofthe upper 'roller is caused,`camplates having-a rectilinear motion maybe'employed, which act analogously 't0 l ating-faces of ..which vare.inclined atfagreate'r the former on the hearings L L, and the openAangle upon the indeed, the equivalents of the o,

When thecorrugations are to be formed bypresses, straight or curved dies with projecting ribsor ledges arerequired, instead ofthe rollers and 'the rings ot' the machinehereinbefore described. For the rest the rangement does notsubstantially differ from the foregoing.V The said vribs or ledges aremade movable on the body of the dies in a similarn'ianner as the coi-rugating-rings on the rollers, and theyfare provided with screws. or otherdevices, such as described, for causing. them vto approach each otherwhile the dies are being pressed together.
